Specific weight of liquid
pecific weight, sometimes referred to as unit weight, is simply the weight of fluid per unit volume. It is usually denoted by the Greek letter γ (gamma) and has dimensions of force per unit volume.

A fluid that has no resistance to shear stress is known as an ideal or inviscid fluid. Ideal fluid is Incompressible, which means the density is constant. Ideal fluid is Irrotational, which means the flow is smooth, no turbulence at all. Ideal fluid is also non-viscous, which means there is no frictRead more

See lessA non-uniform steady flow is through
A non-uniform steady flow is through an expanding tube at a constant rate. Solution: In this flow, the stream changes from point to point in flow direction but does not change w.r.t. time. This flow condition is known as non-uniform steady flow.

The Gauckler–Manning formula is used to estimate the average velocity of water flowing in an open channel in locations where it is not practical to construct a weir or flume to measure flow with greater accuracy.

Back water curve is caused if
It is defined as a maximum increase in water level due to obstruction in the path of the flow of water. The profile of rising water on the upstream side of the dam is called a backwater curve. Hence, the backwater curve is the profile of the rising water on the upstream side of the obstruction.

See lessFlow in pipes is turbulent if Reynold number is
In terms of Reynolds number, the flow is considered to be turbulent when Re > 3500. It is considered fully turbulent when Re > 4000. The following are some key attributes of turbulent flow: Usually occurs at high velocity and low dynamic viscosity.
